Application
Methacrylic acid is used as intermediates to make organic glass, and to make acrylic resin, plexiglass resin and adhesive in the organic industry. In the textile industry, it is used to make fabric treatment agents. It can also be used as a raw material for pharmaceutical intermediates.
Packing
50kg, 200kg drum, 1000kg IBC or ISOTANKs.
Handling and Storage
In order to prevent polymerization, methacrylic acid must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. Methacrylic acid must be stored between 18 and 35 °C, preferably between 20 and 25 °C. To prevent freezing, the temperature of methacrylic acid should never drop below 18 °C. Improper thawing can result in violent polymerization.
